Public Libraries and the Internet 2006

Examines the capability of public libraries to provide and sustain public access Internet services and resources that meet community needs, including serving as the first choice for content, resources, services, and technology infrastructure

Costing Reference: Issues, Approaches, and Directions for Research

The Assessing Quality in Digital Reference project is a first step toward understanding the cost of digital reference services in libraries. This article presents three measures isolated by project participants as being most useful for their immediate needs: total cost of providing digital reference service, the cost of digital reference service as a percent of the total reference budget, and the cost of reference as a percent of the total library or organizational budget. In addition, it reviews selected outstanding issues in the ongoing question of how to determine the cost of reference services in libraries and offers direction for further study toward a general cost model for information servicesInformatio

Libraries Connect Communities: Public Library Funding & Technology Access Study 2008-2009

Based on a survey of public libraries, examines trends in demand for, provision of, and quality of free computer and Internet services and in library budgets. Includes state data and suggestions for improving public access connectivity and infrastructure

Knowing what you know in brain segmentation using Bayesian deep neural networks

In this paper, we describe a Bayesian deep neural network (DNN) for predicting FreeSurfer segmentations of structural MRI volumes, in minutes rather than hours. The network was trained and evaluated on a large dataset (n = 11,480), obtained by combining data from more than a hundred different sites, and also evaluated on another completely held-out dataset (n = 418). The network was trained using a novel spike-and-slab dropout-based variational inference approach. We show that, on these datasets, the proposed Bayesian DNN outperforms previously proposed methods, in terms of the similarity between the segmentation predictions and the FreeSurfer labels, and the usefulness of the estimate uncertainty of these predictions. In particular, we demonstrated that the prediction uncertainty of this network at each voxel is a good indicator of whether the network has made an error and that the uncertainty across the whole brain can predict the manual quality control ratings of a scan. The proposed Bayesian DNN method should be applicable to any new network architecture for addressing the segmentation problem.Comment: Submitted to Frontiers in Neuroinformatic

Video-based Assessments of Colonoscopy Inspection Quality Correlate with Quality Metrics and Highlight Areas for Improvement

Background & Aims Adenoma detection rate (ADR) and serrated polyp detection rate (SDR) vary significantly among colonoscopists. Colonoscopy inspection quality (CIQ) is the quality with which a colonoscopist inspects for polyps and may explain some of this variation. We aimed to determine the relationship between CIQ and historical ADRs and SDRs in a cohort of colonoscopists and assess whether there is variation in CIQ components (fold examination, cleaning, and luminal distension) among colonoscopists with similar ADRs and SDRs. Methods We conducted a prospective observational study to assess CIQ among 17 high-volume colonoscopists at an academic medical center. Over 6 weeks, we video-recorded >28 colonoscopies per colonoscopist and randomly selected 7 colonoscopies per colonoscopist for evaluation. Six raters graded CIQ using an established scale, with a maximum whole colon score of 75. Results We evaluated 119 colonoscopies. The median whole-colon CIQ score was 50.1/75. Whole-colon CIQ score (r=0.71; P<.01) and component scores (fold examination r=0.74; cleaning r=0.67; distension r=0.77; all P<.01) correlated with ADR. Proximal colon CIQ score (r=0.67; P<.01) and component scores (fold examination r=0.71; cleaning r=0.62; distension r=0.65; all P<.05) correlated with SDR. CIQ component scores differed significantly between colonoscopists with similar ADRs and SDRs for most of the CIQ skills. Conclusion In a prospective observational study, we found CIQ and CIQ components to correlate with ADR and SDR. Colonoscopists with similar ADRs and SDRs differ in their performance of the 3 CIQ components—specific, actionable feedback might improve colonoscopy technique

Meeting the Needs of IT Stakeholders in a Northwest Florida State College

Many studies support the important role that two and four-year college programs can play in certification training and as a gateway to the four-year IT degree. In an effort to determine if one Florida Panhandle community college was delivering its intended IT education goals and meeting the needs of local employers, the researchers performed five comparative analyses that stemmed from the overarching research question, “How do IT program learning outcomes compare to the requirements of IT job postings as well as to IT student and faculty perceptions of what is learned and what is taught?” The results of this study, when contextualized with extant literature, suggest that schools are challenged in aligning curricula with IT employers needs especially in clarifying the value of certifications and obtaining meaningful experiential learning opportunities for students as they manage their education and career pathways.ye
